Why 75% Attendance Matters
Universities worldwide enforce **minimum attendance** (often 75% in India & Pakistan, varies in US/UK). Falling below can mean exam debarment — even with good grades.
By Region
The Attendance Formula
Attendance % = (Classes Attended ÷ Total Classes Held) × 100
How Many Classes Can You Miss?
If you are **above** 75%, you can calculate allowed absences:
Can miss = ⌊Attended ÷ 0.75 − Total⌋
**Example:** 40 total classes, 32 attended = 80% attendance. You can miss **2 more** classes before dropping below 75%.
Below 75%? How to Recover
If attendance is low, you need consecutive attendance:
Classes needed = ⌈(0.75 × Total − Attended) ÷ 0.25⌉
**Example:** 40 total, 28 attended (70%). You need **8 consecutive classes** with no absences to reach 75%.
